Starter System Circuit Troubleshooting 

1. PGM-FI, A/T, and Keyless Access Control system DTC check

   -1. Connect the HDS to the DLC .

   -2. Turn the vehicle to the ON mode.

   -3. Check for PGM-FI, A/T, and Keyless Access Control system DTCs with the HDS. If you fail to enter the SYSTEM SELECTION MENU with the HDS, go to the keyless access system symptom troubleshooting

   Keyless Access System Symptom Troubleshooting - Cannot Select On Mode With Keyless Access And With The Keyless Remote Touching The Engine Start/Stop Switch(With Electric Steering Lock)

   Keyless Access System Symptom Troubleshooting - Cannot Select On Mode With Keyless Access And With The Keyless Remote Touching The Engine Start/Stop Switch(Without Electric Steering Lock)

   PGM-FI system 

   DTC Description	Confirmed DTC	Pending DTC

   A/T system 

   DTC Description	Confirmed DTC	Pending DTC	Freeze Frame

   Keyless Access Control system 

   DTC Description	DTC

   Are any DTCs indicated?

   YES 

   Go to the indicated DTC's troubleshooting.

   NO 

   Go to step 2.

2. Starting system check 1

   -1. Select ALL INJECTORS STOP in the PGM-FI INSPECTION menu with the HDS.

   ALL INJECTORS STOP

   With the transmission in P or N, and with the brake pedal pressed, turn the vehicle to the START mode to crank the engine.

   Did the starter crank the engine?

   YES 

   Do the PCM reset in the PGM-FI mode menu to cancel ALL INJECTORS STOP with the HDS.

   NO 

   Go to step 3.

3. Starting system check 2

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Check the 12 volt battery condition. Check the electrical connections at the 12 volt battery, the 12 volt battery negative cable to the body, the engine ground cables, and the starter for looseness and corrosion. Then try starting the engine again.

   Did the starter crank the engine?

   Starter cranks normally

   Repairing the loose connection corrected the problem. Do the PCM reset in the PGM-FI system to cancel ALL INJECTORS STOP with the HDS.

   Starter does not crank engine at all

   If the starter does not crank the engine at all, go to step 4.

   Starter cranks abnormally

   If the starter cranks the engine erratically or too slowly, go to step 6.

   Starter overruns

   If the starter does not disengage from the drive plate when you release the button, remove the starter , and check for the following:

   • Dirty drive gear or damaged overrunning clutch
   • Damaged drive plate
4. Fuse check

   -1. Check the following fuses.

   Fuse	Location
   No. A6 (10 A)	Under-hood fuse/relay box
   No. C31 (7.5 A)	Under-dash fuse/relay box

   Are the fuses OK?

   YES 

   Reinstall the fuses, then go to step 5.

   NO 

   Replace the fuse(s), and recheck. If the fuse(s) blows again, repair the short to ground on the No. A6 (10 A) and/or the No. C31 (7.5 A) fuse circuit(s).

5. Determine possible failure area (starter, starter circuit)

   -1. Make sure the transmission is in P or N.

   -2. Disconnect the following connector.

   -3. Connect terminals A and B with a jumper wire.

   Terminal A	12 volt battery positive terminal
   Terminal B	Starter S terminal 1P connector No. 1 (S)

   Did the starter crank the engine?

   YES 

   Check the following items in the order listed until you find the problem in the circuit:

   • Check for an open in the wire and connectors between the under-dash fuse/relay box and starter cut relay 1 and/or starter cut relay 2.
   • Check for an open in the wire and connectors between starter cut relay 2 and the starter.
   • Check for an open or short in the wire and connectors between the PCM and the TCM.
   • Check for an open or short in the wire and connectors between the PCM and the keyless access control unit.
   • Check for an open in the wire and connectors between the under-hood fuse/relay box and the brake pedal position switch.
   • Check for an open in the wire and connectors between the brake pedal position switch and the PCM.
   • Check for an open in the wire and connectors between the brake pedal position switch and the keyless access control unit.
   • Check for a faulty engine start/stop switch.
   • Check for faulty starter cut relay 1 and starter cut relay 2. 
   • Check for a faulty brake pedal position switch.

   NO 

   Check for an open or short in the wire and connectors between the 12 volt battery and the starter. Test or replace the starter .

   NOTE: Do not inspect the component parts inside the starter if disassembly is prohibited.
6. Starter test:

   Connect the following equipment:

   • Ammeter, 0-400 A
   • Voltmeter, 0-20 V (accurate within 0.1 V)

   -2. Do the STARTING TEST, check the cranking voltage and the current draw from the following service limit table.

   Voltage	Current
   8.5 V or more	380 A or less

   Are the cranking voltage and the current draw within the service limits?

   YES 

   Remove the starter , and inspect its drive gear and the drive plate for damage. Replace any damaged parts.

   NO 

   Check the starter and if there is no problem, check the engine rotational load:The following are assumed as abnormalities of the starter.

   NOTE:

   • Drag in the starter armature
   • Shorted armature winding
   • Open circuit in the starter armature commutator segments
   • Excessively worn starter brushes
   • Open circuit in the starter brushes
   • Dirty or damaged helical splines or drive gear
   • Faulty overrunning clutch
